At Kepler Communications, we're not just imagining the future of on-demand space connectivity - we're leading it!

Our mission is to provide real-time Internet access for space-based assets, enabling a new era of data-driven exploration and innovation. With 33 satellites launched to date, Kepler operates the first commercial optical data relay constellation, enabling real-time, continuous space communications while supporting advanced on-orbit compute and hosted payload capabilities.

Industry-leading technology is only part of the story. What sets Kepler apart is our team: bold thinkers, skilled builders, and passionate problem-solvers who thrive on pushing the boundaries of what’s possible in space. We believe great ideas come from diverse perspectives, and we’re committed to creating an environment where you can grow, lead, and make a global impact.

If you’re ready to reach higher, move faster, and do work that shapes the future space economy - this is your launchpad. Come build the future with Kepler!

What We Offer:

Competitive compensation with a robust equity plan to share in our success.

Comprehensive coverage for health, dental, and vision insurance—including dependents.

Unlimited vacation, supportive parental leave policy, and company-wide holiday shutdown.

Semi-annual company-wide parties and frequent in-office team events.

Relocation packages available for approved roles.

$1,500 annual professional development fund to support your growth.

Fully stocked Toronto office kitchen with snacks, drinks, games and top-notch kitchen appliances.

Town Halls, Celebration Calls, and Company-wide events to stay connected and engaged.

We’re a certified Great Place to Work®, five years in a row!

Kepler is seeking an experienced Embedded Software Test Automation Designer to help ensure the quality, reliability, and maintainability of software across the full development lifecycle. This role is ideal for someone who enjoys wearing multiple hats: part test strategist, part automation developer, part infrastructure builder, and part quality champion.

You will work closely with software, systems, and hardware teams to analyze requirements, define verification strategies, build and maintain automated test systems, and improve the overall efficiency and effectiveness of development workflows. This includes everything from designing test plans and writing automated tests to developing custom HIL solutions, simulators, CI/CD pipelines, and workflow automations.

What success looks like:

Test plans and test coverage are aligned with requirements and risk

Automated tests run reliably in CI/CD and provide fast, actionable feedback

HIL and simulation environments are stable, scalable, and useful to developers

Quality issues are identified early, and regressions are minimized

Engineering teams move faster because test infrastructure and workflows are efficient and easy to use

Quality is treated as a shared engineering responsibility, with this role helping lead that mindset

This is a hands-on role for someone who is passionate about raising product quality while also improving developer velocity through smart tooling, scalable automation, and strong engineering practices.

Key Responsibilities:

Analyze system and software requirements and translate them into effective verification strategies, test plans, and detailed test cases

Design, implement, and maintain automated tests at the unit, integration, system, and hardware-in-the-loop levels

Develop and maintain test automation infrastructure for embedded software, including custom HIL setups, device simulators, test harnesses, and supporting tools

Build, maintain, and improve CI/CD pipelines in GitLab to enable reliable automated testing, regression testing, reporting, and release readiness

Document and report verification results with traceability to requirements

Create and maintain workflow automations and internal tooling using platforms such as n8n, scripting, and other automation frameworks

Write robust automated tests using open source tools such as PyTest, Bash unit, GTest, and other suitable frameworks for the target environment

Review code and test code with an emphasis on reliability, testability, maintainability, and overall software quality

Investigate failures, identify root causes, and work with developers to resolve issues efficiently

Track verification progress, test results, and quality metrics, with clear traceability to requirements where needed

Help define and promote best practices for testing, automation, observability, and software quality across the engineering organization

Identify opportunities to improve developer efficiency and product quality through better tooling, automation, process improvements, and test strategy

Apply static and dynamic analysis tools (SonarQube, Cppcheck, Pylint, CodeSonar) to identify and track defects

Required Skills & Qualifications:

Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field

5+ years of experience in software testing, verification, test automation, or a similar role, preferably in embedded systems

Strong experience analyzing requirements and developing structured test plans and test cases

Hands-on experience building automated test frameworks and infrastructure for embedded or hardware-integrated software systems

Strong proficiency in Python and Bash for test development, scripting, and automation

Experience writing and maintaining automated tests using frameworks such as pytest, bash unit, or similar tools

Experience with CI/CD systems, preferably GitLab CI/CD, including pipeline design, test integration, and reporting

Experience with hardware-in-the-loop testing, simulators, or custom test rigs for embedded devices

Solid understanding of software development workflows, code review practices, and quality assurance principles

Ability to work across disciplines and balance strategic test planning with hands-on implementation

Bonus Points:

Experience with embedded Linux environments

Experience leveraging AI tooling to accelerate development velocity without sacrificing quality

Experience testing software that interfaces with hardware, peripherals, sensors, or communication buses

Familiarity with containerized test environments and development tools

Experience building internal developer tools or workflow automations using platforms such as n8n

Familiarity with static analysis, code quality tooling, and test coverage reporting

Experience in regulated, safety-critical, or mission-critical industries

Knowledge of C or C++ in addition to Python and Bash

Work Model:

This is a hybrid role with a strong remote emphasis. Occasional onsite work may be required to support specific tasks such as hardware testing, system integration, or in-person collaboration.

Salary Range: $131,100 - 181,000 CAD

Actual total compensation will be determined at the Company’s discretion and is based on a variety of job-related factors, which may include, but are not limited to, relevant knowledge, skills, experience, performance, and education and/or training. The Company encourages all qualified applicants to apply, even if the posted salary range does not align with their expectations, as it does not reflect our total compensation package.

Job Type: This is for a current vacancy
